英文摘要	The structure elucidation of heavy Grignard reagents (RAeX, Ae=Ca, Sr, and Ba, X=halides) has been greatly strived after, mainly because of their inaccessibility and remarkable instability. The synthesis of a series of butadienylcalcium compounds is presented, including 1-calcio-4-lithio1,3- butadiene, 1,4-dicalcio-1,3-butadiene, and a Ca-4[O]inverse crown ether complex, via the reaction between 1,4-dilithio-1,3butadienes and calcium iodide in THF. Single-crystal X-ray analysis of these unprecedented heavy Grignard reagents revealed unique structural characteristics and bonding modes. Preliminary reaction chemistry was investigated. This study provides a novel class of alkenyl heavy Grignard reagents and a useful synthetic strategy for otherwise unavailable reactive organometallic compounds.; Natural Science Foundation of China [21572005, 21372014]; SCI(E); ARTICLE; 31; 9188-9192; 56
